All hardware devices experience bugs and need debugging. Android devices in specific are exceptionally complex with several hundred gigabytes of source code, dozens of components, and wide range of uses. In this article we will explore the different facilities and tools available to debug Android based devices and produce robust systems that can handle a wide range of applications from smart fridges, to payment terminals, and of course mobile phones.
Sometimes, C/C++ projects have a long development cycle. When working on such a project, it can be easy to take our development environment for granted, and forget about the effort invested in its bring-up. The build environment works like magic, the test framework is neatly integrated, and the CI/CD pipeline relieves us of tedious, repetitive tasks.
The security camera is one of the most prevalent IoT devices being used today. Ironically, one of these cameras' primary vulnerabilities is that they may be stolen or damaged - you need protection for the security cameras. Having gadgets that operate independently saves time since you may leave them to do the job they intended. However, remotely placed, unsupervised equipment must be monitored, and the most effective method is through the use of an automated monitoring system.
The Internet of Things (IoT) - is a number of physical devices connected to one network that enables the system to interact with the external world. A great deal of the work surrounding IoT is monitoring, as it’s impossible to react without knowing the situation. For example, we might build a greenhouse system for agriculture that can maintain optimal conditions for growing crops. For this purpose, we need to have sensors picking up information about the temperature and humidity.
I’ve been a firmware engineer at two wearable companies in the past, Pebble and Fitbit, and there was always one class of customer support tickets and user complaints that never went away: issues around battery life. It was a constant game of whack-a-mole with every new firmware version introducing a battery regression.
